J'OHN DESMOND, OF CHICAGO, ILLINOIS, ASSIGNOR TO ARTIZAN BRASS COMPANY,OF

' CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

' LIQUID-DISPENSER.

To all whom it may concern:

Be it known that I, JOHN DEsMoNn, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Liquid-Dispensers, ofwhich thefollowing is a specification.

My invention relates to improvements 111 liquid dispensers. It hasparticular reference to devices of this character wherein liquid is heldwithin a receptacle or reservoir under pneumatic pressure and projectedtherefrom in=a solid stream, or in an atomized spray as its use mayvary.

One of the objects of my invention is t.o provide a device. wherein-aspraying liqu d, such as an insecticide, ora cleaning liquid, such asgasolene or the like, or a very finely divided powder may be containedunder pneumatic pressure and sprayed or projected against or on objectsin desirable quantities and at convenient times.

Other and further objects of my invention will become apparent topersons skilled in the art from the description and drawings,

wherein- Figure 1 is'a longitudinal section of the device; and Fig. 2 isa similar view of a fragment of the device, showing a spraying nozzleinserted therein, instead of the solid, stream nozzle shown in Fig. 1.

In both views the same reference characters refer always to like parts.

The reservoir or cylinder, 5, may be made of a suitablemetal, suchasbrass or the like,

and is preferably provided with bumped ends. p j

A handle, 8, is secured to an end of the casing, as shown,,by means ofwhich the evice may be manipulated. A nozzle, 9..

for projecting a solid stream, shown in-Fig. 1, is screwed into athreaded opening, '10. It is provided with'a clearfront opening and witha relatively long bore, as shown at 11, for guiding'andretaining'thevalve stem, 12. At the inner end of thebore, 11, a valveseat, 13, is provided for rece tion' of .the needle valve, 14, on theend of t e valve stem 12. Lateral openings, 1515, admit liquidor powder,as the'case may be, to the nozzle proper. A gland, 16, is secured to theother i packing thevalve reciprocation and to" render the casing"substantially pressure-'- end of the casing-for stem to permit its easytight. Packing, 17, as usual in suchdevices,

Specification of Letters Patent. Patented Del}. 10, 1912., Applicationfiled January 10, 1910. Serial is employed for this purpose. is securedto the valve stem, 12, 19, against which the open spring, 20, abuts fornormally the valve closed, as clearly shown. The outer end ofthe valvestem, 12, carries a handle which is limited in its reciprocatingmovement by the. handle 8. When the handle, 21, is moved its fullextent, or until it comes into actual contact with handleS, it has notbeen moved sufficiently to withdraw the valve, nozzle, 9, and thus thevalve cannot be displaced with reference to its seat. A filling cup, 22,is screw-threaded'and extends into the cylinder about one third of' theway across the diameter thereof so as to leave an unoccupied space aboveits lower edge when filling the .device with materialto be 'applied inthe manner described." A stopper, 23, is screw-threaded into said cupand when inserted therein tightly closes the same. An air valve, 24,similar to valves of this character used on the cylinder, therein. Theuse and operation of-the device is as as by a pin, compression 5, andcontrols an air opening with, the material to be dispensed, it should beheld in the position shown in the drawing, and the liquid,for othermaterial poured in through the cup, 22. The reservoircannotbe filledbeyond the lower'edgeof the cup, leavingan unfilled space between thelower edge of the'cup andthe top of the reservoir. The device is thenconnected to an air pump, vthe valve, 24, and air under'pressure isthereby admitted into thefotherwise unoccupied space Within thereservoir. The air may be compressed to any pract'cable limit, sayinpractice anywhere from 2 square inch, more or less. The instrument isnow ready for use. If it has been charged wit-h gasolene or the like,and compressed air, itshould beheld in the position shown a downwarddirectionand .themha'ndlef2l, compressed or drawnitowardthe handle 8.-he valve is thusv opened andthel liquid constream, against a usedfor'other-purposes. When the nozzle maintaining tents'will beviolently'pro ect'ed, in a solid A collar, 18,

1% from the bore, 11, of the 'pneumatictires, is secured to follows:When the reservoir is to be filled or compressed air reservoir at topounds per or with its nozzle end pointing slightly in surface to becleaned, such for-1nstance as the oily surfaceof an enginefi H or thelike, or the liquid in astream may b64 9', shown in Fig. 2, issubstitutd for the nozzle 9, the liquid will be atomized or sprayed. Thedevice may be charged with a suitable insecticide, such as the Bordeauxmixture, and the otherwise unoccupied space may be filled with air underpressure from a source of air supply. The air may be passed into thecylinder through the nozzle, 9 or 9, when the-valve thereof is retractedby pressure applied to the handle, 21, in which event the check valve,24, will not be necessary. The device thus loaded may be taken to thetops of high trees, from which position limbs and branches, inaccessibleby the usual spraying devices with hose attached, may be convenientlyandthoroughly suitable closures, in combination with a nozzle for saidoutlet providing a small bore, a valve. seat at the inner end thereof,and a cylindrical valve-stem-guiding portion extending inwardly fromsaid valve seat, a valve stem extending through the opposite end of.said cylinder, at its inner end shaped to coact with said valve seat andat its outer end having a portion extended" laterally to provide ahandle movable to move the stem, and a stationary handle mounted on saidcylinder, by which said cylinder may be pointed in any desireddirection, said handle for the valve stem being spaced from thestationary handle a distance less than the length of said cylindricalguiding portion of the nozzle, whereby said nozzle bore may be opened bygrasping and drawing together said handles, said stem being in allpositions guided at its inner end so that lateral pressure may beconveniently applied thereto, adjacent the handle, to aid inmanipulation of said cylinder by suitable gripping of said handles.

In testimony whereof I hereunto set my hand. in the presence of twowitnesses.
